TMZ and NE have gotten it right more times than I care to know.
As for residuals, Erin and everyone else connected to HD signed contracts before the VHS and DVD era. They had no concept of that being a money-maker. It was all about syndication, and even that doesn't guarantee residuals. Even if she were to be earning residuals, who knows how much she is actually getting. Maybe she likes to live beyond her means. Maybe she and her spouse don't have a great income, who knows. But if she is being evicted, that can easily be verified by NE or TMZ, which is why I do not doubt the story.
